[80." Distance of pole from side "],[" line "]

A North pole of 40A-m is palced 20 cm apart from a South pole of 80A-m . Calculate the distance of a point from the Sourth pole on the line joining the two poles where the resultant field due to these poles is zero

Construct an angle PQR=80^(@) . Draw a line parallel to PQ at a distance of 3 cm from it and another line parallel to QR at a distance of 3.5 cm from it. Mark the point of intersection of these parallel lines as A.

From a point on the ground at a distance a from the foot of a pole, a ball is thrown at an angle of 45^@ , which just touches the top of the pole and strikes the ground at a distance of b , on the outer side of it. Find the height of the pole.

If u represents object distance from pole of spherical mirror and V represents image distance from pole of mirror and f is the focal length of the mirror, then a straight line u=v will cut u versus v graph at

A person observed that the angle of elevation at the top of a pole of height 5 metre is 30^(@) . Then the distance of the person from the pole is :

Two poles of equal heights are standing opposite to each other on either side of the road which is 80 m wide. From a point P between them on the road, the angle of elevation of the top of one pole is 60^(@) and the angle of depression from the top of another pole and distances of the point P from the poles.

Two poles of equal heights are standing opposite each other on either side of the road, which is 80m wide. From a point between them on the road, the angles of elevation of the top of the poles are 60^(@) and 30^(@) , respectively . Find the height of the poles and the distances of the point from the poles.
